Glossary of Terms

IBTTA’s transportation Glossary of Terms is an ever-changing list of terms used within the transportation and tolling industry. The Glossary was updated in August 2018.  If you have suggestions for future additions, please contact us.

The Council of Platinum Sponsors (CoPS) TollMiner & Glossary Working Group was created to improve definitions of toll facility concepts that are used in the IBTTA TollMiner Data Visualization tool. Since the TollMiner data and structure are closely linked to the IBTTA Glossary, a review and draft update of the glossary was performed during 2021.
